G'day,
This is on Pentangle's "Solomom's Seal" album. While "Sally Free & Easy" is attributed to Cyril Tawney, all other songs are listed as (Jansch-Renbourn-Thompson-Cox-McShee). I think we are meant to infer that they are all either trad arr, or written by Pentangle.

While a couple of songs on this album sound fairly recent, I'm sure they didn't write "The Snows". Therefore it's trad????

Cheers,
Alan
